Journal ArticleDOI
Electrospun polyacrylonitrile nanocomposite fibers reinforced with Fe3O4 nanoparticles: Fabrication and property analysis
Di Zhang,Amar B. Karki,Dan Rutman,David P. Young,Andrew Wang,David L. Cocke,Thomas H. Ho,Zhanhu Guo +7 more
TL;DR: In this paper, a uniform, bead-free fiber production process is developed by optimizing electrospinning conditions: polymer concentration, applied electric voltage, feedrate, and distance between needle tip to collector.
Journal ArticleDOI
Carbon-stabilized iron nanoparticles for environmental remediation
TL;DR: Ferromagnetic carbon-coated Fe nanoparticles fabricated at a mild temperature demonstrate a strong ability to effectively remove more than 95 wt% of Cr(VI) in waste water via carbon shell physical adsorption, which is much higher than the commercially available Fe NPs.
Journal ArticleDOI
Conductive Polypyrrole/Tungsten Oxide Metacomposites with Negative Permittivity
Jiahua Zhu,Suying Wei,Lei Zhang,Yuanbing Mao,Jong Eun Ryu,Pallavi Mavinakuli,Amar B. Karki,David P. Young,Zhanhu Guo +8 more
TL;DR: In this article, a quasi-three-dimensional variable range hopping (VRH) conduction mechanism is used for electron transportation in polypyrrole (PPy) nanocomposites reinforced with tungsten oxide (WO3) nanoparticles and nanorods (NRs) by a surface-initiated polymerization method.
Journal ArticleDOI
Polypyrrole/Silicon Carbide Nanocomposites with Tunable Electrical Conductivity
Pallavi Mavinakuli,Suying Wei,Qiang Wang,Amar B. Karki,Sanjay R. Dhage,Zhe Wang,David P. Young,Zhanhu Guo +7 more
TL;DR: In this paper, a facile oxidative polymerization approach using p-toluene sulfonic acid as a dopant and ammonium persulfate as an oxidant was used to construct conductive polypyrrole/SiC nanocomposites.
Journal ArticleDOI
Polyaniline-tungsten oxide metacomposites with tunable electronic properties
Jiahua Zhu,Suying Wei,Lei Zhang,Yuanbing Mao,Jong Eun Ryu,Amar B. Karki,David P. Young,Zhanhu Guo +7 more
TL;DR: In this paper, a facile surface-initiated-polymerization (SIP) method was used to construct polyaniline (PANI) nanocomposites reinforced with tungsten oxide (WO3) nanoparticles and nanorods (NRs).
